When you see a segment line like this in a PNR, the airline code identifies Aer Lingus:
2 EI 587 Y 15JUL 2*JFKLHR HK1 800A 2000P
The two-letter code EI at the start of the segment line is Aer Lingus's IATA code — every flight segment operated by Aer Lingus in a GDS PNR (Amadeus, Sabre, Galileo, or Worldspan) begins with this code, followed by the flight number.
Aer Lingus is a irish flag carrier, based in Ireland. Its ICAO code, EIN, is used for air traffic control and flight planning, while its radio callsign is “SHAMROCK”.
Once a EI segment is sold, the fare quote and ticketing entry differ by system. The starting point in each is:
Amadeus: FXP Sabre: WPNCB Galileo: FXP
Each of these prices the itinerary using the lowest applicable fare for the EI segment(s) in the PNR — the exact fare basis and rules still need to be checked against Aer Lingus's current fare filing, since GDS pricing reflects what's filed, not a fixed rate.
Like most airlines, Aer Lingus's fare classes follow the standard GDS booking-class letter system. See our complete booking class guide for what each letter (F, J, Y, and so on) typically means.
